This is a server for IRC chat. It is written in node.js (a server-side version of Javascript), so it is both fast and scalable - much faster than, say, Apache with PHP! It can support thousands of connections at once. The IRC server has a user system: users can sign up from a CAPTCHA-protected Web interface, and then log into the server with their username and data. They can connect from as many devices as they wish; the server will work seamlessly.
